Patent JP-H03207266-A (JP)
Title: Ringing choke converter
Inventor: MATSUMAE HIROSHI
IPC: H02M3/28
Filed: 1989-12-29
Abstract: PURPOSE:To stabilize output voltage by equipping it with a transformer, a field effect transistor(FET) for switching, a capacitor for on time adjustment, an FET for driving, an auxiliary capacitor for on time adjustment, and an FET for predriving. CONSTITUTION:When an FET 2 for switching is supplied with currents, the voltage approximately proportionate to the input voltage is induced in the winding 1b for feedback of a transformer 1, and the FET 2 is turned on. The output voltages at both ends of the winding 1c for output of the transformer 1 drop and fluctuate by the effect of the turn-on time of the FET for switching, and others. Thereupon, by turning on or turning off an FET 17 for switching according to output voltage, the composite capacity between a capacitor 15 for on time adjustment and an auxiliary capacitor 16 for on time adjustment is changed, whereby the one period of an FET 14 for driving is controlled.

Title: Intake-air controller for internal combustion engine
Inventor: MAEDA SATOSHI
IPC: F02B27/02
Filed: 1989-12-27
Abstract: PURPOSE:To lengthen an inlet pipe and lower the total height of an engine by forming a suction system with four divisions, i.e., right and left inlet manifolds and right and left air chambers, which are formed as an integrated body together with an air-intake passage. CONSTITUTION:A suction system is formed with four divisions, i.e., right and left inlet manifolds 35a and 35b, and right and left air chambers 29 and 30, which are formed as an integrated body together with air-intake passages 31 to 34. Thus, the intake-air, which flowed into a collector 28, flows into the right or left chambers 29 or 30. At the time of a low or medium engine speed, by fully closing closing-control-valves, which are arranged on the high-engine- speed, air-intake passage (361 to 364) side, the intake-air from the air chambers 29 and 30 is sucked into the combustion chamber via both air-intake passages 31 to 34 and intake-air passages 371 to 374 for a low engine speed. In this case, since the distance between the right bank and the left bank is large enough, the air-intake passages 31 to 34 can sufficiently be lengthened. In addition, since the suction system is made up of four compact divisions and is of a flat shape, the total height of the engine can be lowered.

Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To eliminate a risk for developing crack of a soldered part by increasing the plate thickness of a pressure contact part for pressure contacting a bus bar or the like at the prescribed contact pressure, while reducing the plate thickness of a fixing part for the alleviation of stress. SOLUTION: The thickness t2 of a pressure contact part 5a is made large, and the thickness t3 of a fixing part 5b is made small so as to keep a relationship of t2>t3, thereby enabling the thick pressure contact part 5a to pressure contact a bus bar 3 or the like at the prescribed contact pressure, and alleviating stress via the deflection of the thin fixing part 5b. A female terminal 5A has the plug part 5d of a fixing part 5b inserted in the mounting hole of a printed board, and the lower end of the fixing part 5b and the plug part 5d are soldered to both sides of the printed board.  As a result, the thick pressure contact part 5a having the thickness of t2 can pressure contact the bus bar 3 or the like at the prescribed contact pressure, and stress is alleviated via the deflection of the thin fixing part 5b having the thickness of t3, thereby eliminating a risk for developing crack in a soldered part.

Filed: 1992-12-24
Abstract: PURPOSE:To discriminate the upper/lower relation of plural layers by a lightness which is different at a place where wiring, etc., are overlapped by generating a second picture where the lightness changes successively from a lower side toward a higher side by picture generating device. CONSTITUTION:In the layout of a semiconductor integrated circuit the lightness becomes dark successively from the lower side toward the higher side. In the layout of the other semiconductor integrated circuit, the lightness becomes light successively from the lower side to the higher side. In this case, at the place where wiring is overlapped in a direction perpendicular to a paper surface, wiring belonging to the lower side is not displayed. Thus, a second layer 2 is displayed at a place where a first layer 1 and the second layer 2 are overlapped, a third layer 3 is displayed at a place where the second layer 2 and the third layer 3 are overlapped and a fourth layer 4 is displayed at a place where the third place 3 and the fourth layer are overlapped. The lightness is made to change successively from the lower side to the higher side like this so that wiring belonging to the lower side is not displayed at the place where wiring is overlapped.

IPC: C09C3/06
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To carry out the compositing or surface modicication of solid particles and enable the content of fine particles to be freely adjusted by fixing fine particles (child particles) to the surfaces of core particles (mother particles) and causing the crystals of the fixed fine particles to grow. SOLUTION: Cellulose or its deriv., starch or its deriv., a synthetic polymer (e.g. nylon), a metal powder (e.g. a nickel or iron powder), or an inorg. powder (e.g. an alumina powder) is used as the mother particles; and an inorg. or org. compd. having crystallizing properties, as child particles. The child particles are fixed to the surfaces of the mother particles by a mechanical method, such as an impact method in a high-speed air flow. When calcium monohydrogenphosphate (CaHPO4 ), having a very low water solubility, is used as the child particles, the crystal growth of fixed child particles is conducted by a solid-liquid reaction method in the supersatd. state.  For instance, a calcium hydroxide suspension is reacted with pyrophosphoric acid in an aq. soln. adjusted to a pH of 4.5-5.8, pref. 5.7, thus forming CaHPO4 and causing the crystals of CaHPO4 to grow while using CaHPO4 fixed on the mother particles as crystallization nuclei.
